itt the front end of tlieftnnli c. roller 1l journaled in the plates l. Between the roller 11 and the rear end of tlie tank.' a plu.- rality of pairs of rollers are journeled in the plates 1a, each pair comprising?,r a roller 13 and a roller 1l disposed parallel with, but

just belouY and slightly forward of the roller 13. Between each pair of rollers 13 und 111, e roller 15 iS journeled between tbe plates 1n and slightly above the rollers 13.

An endless eonveyer passes rearwardly from the roller 11 over the first roller 13, under tbe roller 13 and downwardly and for'- u'ordly over the roller 14. ci the first pair, then rearwardly and upwardly over the -succeeding' roller 15, tlien similarly to the suo needingq pairs of rollers 13 and 141-, and tlie succeeding rollers 15. lroin the last peir tlie conveyer passes upwardly over tlieroller 5, tlien forwardly over the roller 6 and down into the tank through which it passes forwardly to tlic roller 11 guided by suitable rollers 22 and Q3 journeled in the plates 1U'.

bar 16 of fiber or other suitable material extends transversely of tlic conveyer just above each of the rollers 15 and slightly spaced above the conveyor. The ber 16 is provided et its opposite ende 'Witli arms 1 adjustable through bearings 18 carried by braclrets 19 which are secured tothe side wells oftlie tank, and-the erniswinay be se- -cured in adjusted. position by set screws 9.0.

Between eaeli pair of rollers 13 and lllond the succeeding roller 15, is e t atreverse bar 21 wliicli resclies almost down to tbe conn Voyer, but a space exists between tlie bottoni ot tbe bar and tlie conveyer.

.ett the rear end oit the apparatus, a pipe 2liextends transversely tlirontg'li the tanlt end it is perforated es at tt some snit able point, preferably attlie forward end olf tbe apparatus, is a pipe '26 provided with at discharge branch 27 and water inlet con nection Q8 controlled by e relire 9,9.

tt the forward end of 'tlrre apneratue en inclined leed board 83 is disposed end' .is adapted to receive the .material to betreeted through a pipe 3ft Wliicli leeds from a series of mixing' chambers. rlliebtnd provided with e plurali ty oli' pointed fingers 35i directed upwardly and pivoted at their lower ends 86, the purpose ot the tine-ers beinofto spread tlie materiel as it dotre. dou/n 'lf-lie boord.

Extending along theinner side of one of the walls of the tunlris a leunder 3l from which u pluruliiy of pipes 32 leed into e luunder .30 extending along `the outside of the well. v

ln operation, ihe ore is preferuhly'reduced io u pulp in e series oi' mixing chambers, with which ehe present inyenion has nothing ro do and which are not shown in *che drawings. pulp fed to Jche epperutus may or muy not include o. substance to enhence the floteion of the 'mineral particles by the phenomenon of surface tension, ohe use of suchv substance being dependeniJ upon the nature of the ore under ihreatment. The pulp as it flows down the board 33 is spread entend is conveyed to theconveyer 12 on a transverse line which is alcove the level of the water with which the tank has heen'previously filled from the water inlet 28. The materiel denosiied upon the eon Vey-er is chen carried rearwardly, 4sind loe cause the roller l is below isne roller il, the oonveyer "posses ungulerly downward ihrou'h he surface oi* he weleer. fis the' msreiiwl strikes the surface the weisen the phenomenon of surface tension will cause the mineral sriiclcs in the ore to iou upon he surface or the wuier, because nuving heen first exposed to sir und then brought 'to iheqsurfuce of wuier' hey are acted upon by the -ohuiornenon oi surfe-ce 'tension and are caused to iiost.

Referring to Figs. il, 5,

Adjacent the front end ov the' apparatus a. roller 4A is journaled, und resi I wurdly of it and below the water Vline j'ournsied u roller 55. Rearwardlyof the roller v55 two rollers 53 are journuled in brackets 54, and at such e, height as to' carry u conveyer passing over them above the surfece of water in the tank. At the rea-r end and outside of the tank is avroller 45. adept-f e geur 'Jarsiu d ed to be positively drivenx by 47, 48, 49 und 50. A trough 46 is disposed below the roller 45.

and near each end with dede'ctors 69. lt

Vwill be noted thattbe lips (it extends over the surf-are of the conveyor. ening downwardly from each launder isla pipe 66 connected by a T 65 with al pipe 64. A pipe 60, controlled by a valve (33, also extends longitudinally oi the tank, but it is provided 'with a plurality of Ushaped portions eX- tending transversely ot the tank so as to extend along the opposite sides ot the respective rollers 55, which are provided with ribs 62 to prevent close contact between the rollers and the conveyor. A'perforated pipe 72 extends transversely of the tank adja- Cent the roller 45.

The general principle of operation of the 2o modified apparatus is substantially the same as that of the form first described. The pulp formed by mixing the ore with water and, if desiredg'with some substance to en hance the flotation power of the mineral particles, is flowed down the board Lil on' the rearwardly moving conveyer 43. As theI ma-` terial, in flowing down the board, first ystrikes the surface of the water, a large separation of mineral particles from the ga'ngue gij/"takes place,- due to the fact that the'particles' have been exposedon the board to the air so that when they meet the surface of the water the phenomenon of surface tension is Veffective/to cause them to float. The

remaining gangue, with some mineral par-l ticles ymechanically carried thereby, is .conveyed rearwardly into the water by the conveyer and under the First roller 55, the ribs on the roller holding the conveyer out of '40 closecontact to allow the passage of the pulp. The continued movement ot the con veyer exposes the ulp again. to air the pulp being thinly distributed by the b2b 5e :ma

its exible strips, and as it passes from rollers 53 which have lifted the conveyer from thewater, the conveyer passes downwardly angularly through th surface of the water and a further separation f the mineral parl ticles takes place. The separation may be continued by providing the apparatus with the desired number of similar rollers. .The

gangue is'iinally dumped into the trough 46, the conveyor being., at "h esame time, Washed -by a4 tangential stream from the n pi 72.

t is found, in practice, that an increase in the purpose of causingI the mineral particles floating upon the surface to tlow into thc launders 67, whence they ard discharged. t will be obvious that many changes may be made. in the apparatus without depart 70 ing from my invention.
